“…In addition, because of desirable magnetic properties (15 emu/g), it is easier to separate sorbent from sample and realize recycling than nonmagnetic MOF. From the analytical aspect, the linear range and LOD of the proposed method were approximately the same or better than those of some other methods, which represents the promising future of our present MMOF for determination of AMP from complicated cow milk samples [ 3 , [41] , [42] , [43] ] ( Table 3 ). Moreover, the prepared MMOF was compared with some commercial sorbents presented in Table 4 [ [44] , [45] , [46] , [47] , [48] , [49] , [50] , [51] , [52] , [53] , [54] ].…”
